Shoemaker states that even though the professional cleaning industry tends to be less affected than other industries during financial meltdowns, we are no longer immune.

She notes that a product specializing in a single attribute is perceived to be superior in that attribute relative to an all-in-one product having the same attribute but multiple other features as well.

Shoemaker adds that although there may not be one correct answer as to whether to specialize or offer multiple services, an example of how some building service contractors (BSC) grow, offer more services and benefit from two very difficult periods may provide some guidance.

According to Shoemaker, many companies once offered additional services but found it best to let them go and just specialize in what they do best: Cleaning.
